Has anyone tried to run two CLI's at the same time in a single P4 system
that has a Hyperthreaded CPU?  Do the two argue over resources?

It works fine, yes they do argue and that means that each workunit
takes a bit longer but since you are doing 2 at a time it more than
makes up for it.
Use something like SetiDriver to do it, it is easier.

In general, how much slower is WU results than when just one is run?

Each single WU is slowed slightly. However, this is more than made up by gaining a higher overall WU throughput (more WUs/day).

The 'theoretical' maximum improvement in resource useage as claimed by Intel is "approximately 30%".
